After watching the film, I thought the lost thing represented childhood or imagination. In the narration at the beginning, the narrator said that he used to know a lot of interesting stories but couldn't remember any of them except for the time he found the lost thing. No one around him didn't seem to notice the lost thing or maybe they weren't able to see it. The concept might be we lose our personality when we grow up. The houses, streets, trains, and clothes of people were very similar. It was if they were controlled to do that way. This movie reminded me of Peter Pan, especially the part where the boy finds a place to go for the lost thing. The world there must be a fantasy or a dream yet the boy didn't follow the lost thing and go in as well. Perhaps he thought he will be trapped there forever and never be able to go back to his world.
To tell the truth, I was pretty freaked out by the movie. I couldn't feel any life from the people in the movie except for the main character. In other words, I felt nothing from the extra characters. The world so different yet somehow closely related to the world which we live in now makes me feel uneasy and think about the differences and the lags between them even though it 's not real.
